Akos Kiss d161e2d9ed Disable libjerry-math by default (#4428)
Normally, it is more usual and safe to use a toolchain's native
math library. Especially, if multiple components of a project use
math functions, in which case all components should be linked
against the same libm.

The libjerry-math can be used, of course, but as it needs extra
care and consideration, it should be opt-in.
